However , there are only a few steel structuresdesigning software in accordance with chinese code for structural designing in our country now . specially , there is few steel structure designing cad software about portal lattice rigid frames 但與此同時,緊密結(jié)合我國規(guī)范的鋼結(jié)構(gòu)cad軟件的開發(fā)同國外相比卻并不完善,對工程中應(yīng)用較多的門式格構(gòu)剛架很少涉足。
1 summarization at present , super - length tall buildings are ever - increasing by popular . expansion and contraction joint is not supposed to be located or at least frequently located in average buildings for the requirements of their functions . the longest space between two expansion and contraction joint , which is set in code for structural design is frequently exceeded in cast - in - place frame structure 目前超長高層建筑日見增多,由于功能以及使用上的需要,要求不設(shè)或少設(shè)伸縮縫,結(jié)構(gòu)設(shè)計規(guī)范對現(xiàn)澆框架結(jié)構(gòu)不設(shè)伸縮縫的最大間距的規(guī)定常常被突破,這就需要考慮溫度對結(jié)構(gòu)的影響。
